Keystone K-LOK Figure 360/362&370/372 Performance Butterfly Valves

Butterfly Valve,Keystone K-LOK Figure 360/362 and 370/372 high performance butterfly valves are rated to ASME Class 150 and Class 300, and provide bi-diectional, drop-tight closure. These valves are available in a variety of materials to optimize reliabiliy, no matter the application.

FEATURES:
• K-LOK polymer, elastomer, and fire-safe seats provide bi-directional, drop-tight closure in vacuum and throughout all pressure ranges, as well as at full rated differential pressure. A variety of materials allows optimum seat life in all applications.
• Blow-out proof shaft in accordance with API 609 provides increased operator safety.
• Integrally cast mounting pad provides direct mounting of many actuators.
• Rocker-shaped gland bridge compensates for uneven adjustment of gland nuts reducing packing leaks.
• Extended neck allows for two inches of pipeline insulation.
• Flattened body bore at shaft journal ports positions shaft bearings near disc, providing maximum shaft support resulting in reduced wear and longer life.
• Disc taper pins are tangentially positioned half in disc and half in shaft, placing them in compression rather than shear, which eliminates potential for failure.
• Integrally cast disc position stop perfectly locates the disc in seat, achieving maximum seat and seal life.
